ABSTRACT:
A crevice cleaning tool having an elongated hollow body portion extending between a first end configured for attachment to a wand of a vacuum cleaner and a second end providing an opening for passage of vacuum cleaning air. The body portion has a base section slidably coupled to an extension section for movement between a retracted and extended position and a locking mechanism selectively locks the extension section to the base section in each of the retracted and extended positions. The body portion includes a first air channel for providing passage of vacuum cleaning air through the body and a second air channel adjacent the body portion extending to the opening of the second end to provide a secondary air inlet into the body portion. A passageway passes between the first and second air channels for providing fluid communication therebetween and to prevent blockage of vacuum cleaning air through the opening of the second end into the body portion.
